Our Naturepedic Cotton Classic 150 Coils Crib Mattress has held up wonderfully. As of the date of this article, we’ve been using it for 16 months. For more context, our child has always been on the high end of the growth chart for height and on the low end for weight. We’ve used the mattress fairly frequently and consistently (most naps and most nights have been spent in the crib, up until 15 months where we started preschool 3x week).
When we purchased the mattress, most of the negative reviews we saw were related to the mattress sagging, but we haven’t experienced this at all.
There was also no “smell” when we first received and opened the mattress.
16 months later and our mattress is still like-new!
